Is it possible to cluster overlapping markers dynamically, as you zoom out on the map?

[oysteinarsnes]

I’m showing lighning events on a geomap, and it works pretty well, but when the events are very close to each other, and very nearly overlapping, I’d love for those datapoints to share a preferably larger icon. I couldn’t find a simple option for that, but would it be possible to acheive it by some other (more advanced) method?

To illustrate what I mean. Here on zoom level 13, the markers are fairly spread out, but there are some clusters that could preferably share an icon for improved readability:

At zoom level 8, they should all preferably share one single icon:

I noticed that when I place my coursor on a cluster, Grafana is at least aware that there are more than one marker close-by and merge them in the tool-tip:

here are a couple of things that might help
using stock geomap

Geomap | Grafana documentation

or maybe using leaflet clustering (this would require the use of the business text plugin Leaflet.js | Volkov Labs)
Leaflet.MarkerCluster 0.1 Released - Leaflet - a JavaScript library for interactive maps

Thank you for the suggestion. Not sure I’ll be able to figure the Leaflet plugin out yet, but will definitively try.

I was considering using the heatmaps instead (I should have mentioned that in the OP), I think it looks cool. I just wish I could decide the temperature color range myself - I’d rather avoid the reds, or have the greens replaced by purple (Just a minor aesthetic preferrence, not a big deal).

Mapgl plugin has clusters out of the box

beautiful!

but there seems to be an issue @vaduga

these above points sum up to 9 when scrolling out.

Great you’ve managed to get some points on it so fast!
There s a misguiding issue with size units in mapgl. They’re in meters, not pixels. So to make it visible on small zoom levels you’d have to make points as big as 500 meters in size, for example.
The sum up question you have is maybe caused by the same issue - you probably have 9 points but on a distance? And you don’t see the 9th because it is not close enough to get into a cluster and too small to be seen separately. Just a suggestion

[oysteinarsnes]

Thank you, looks really promising for me. And thank you too @yosiasz for setting up a demo so fast.

I’ll probably need more than a couple of hours myself though

(Might have to hunt down an admin first too, unless I’m cleared to install plugins myself, not sure)

I’ll mark it as a solution, because it looks like it could be.
